Greedy modularity maximization
WebGreedy modularity maximization begins with each node in its own community and joins the pair of communities that most increases modularity until no such pair exists. This function maximizes the generalized modularity, where resolution is the resolution parameter, often expressed as γ . See modularity (). Parameters: GNetworkX graph WebThis inhomogeneity of connections suggests that the network has certain natural divisions within it. Communities are often defined in terms of the partition of the set of vertices, that is each node is put into one and only one community, just as in the figure.

WebModularity maximization One approach to finding such a partition is to define a function that quantifies the quality of a set of partitions, and then adjust the partition to maximize the quality. One popular quality measure is called modularity. WebOn the basis of such results we consider maximization of the modularity to be perhaps the definitive current method of community detection, being at the same time based on …
